This file contains the USB control endpoint management routines corresponding to the standard enumeration process (refer to chapter 9 of the USB specification). This file calls routines of the usb_specific_request.c file for non-standard request management. The enumeration parameters (descriptor tables) are contained in the usb_descriptors.c file.
